a sum of RS 500 is in the form of denominators of RS5 & RS 10..if the total no. of notes is 90 ,find the no. of notes of each type................ do it by process will be mark as best

Answers

let rs.5 denominations be x , then rs 10 denominations will be 90-x

then total amount 5x + 10(90-x) which is rs.500

5x + 10(90-x) = 500

900 - 5x = 500
400 = 5x
therefore x = 80
therefore no. of rs.5 is 80
no. of rs.10 is 90-x = 90-80 = 10

67% of 8.7 = ___ estimate

Answers

The answer is 5.829 but with and estimate... 6

Final answer:

To calculate 67% of 8.7, we convert 67% to its decimal form, 0.67, and multiply it by 8.7, getting an estimated value of 5.83.

Explanation:

To calculate 67% of 8.7, we should multiply 8.7 by 0.67 (which is the decimal equivalent of 67%).

Let's do the calculation:

Convert 67% to decimal form: 67 / 100 = 0.67
Multiply 8.7 by 0.67: 8.7 × 0.67 = 5.829.

So, 67% of 8.7 is approximately 5.83. This is an estimate, since we rounded the final answer to the nearest hundredths place for simplicity. As always, check with your teacher or test instructions for how many decimal places they want you to round to.
